<p>PURPOSE:To express that a constructed equipment is to be newly established after removing an existing equipment by clearly demonstrating that the equipment in subject to construction is related to a newly established construction in displaying the existing equipment and the equipment subject to construction in a drawing in the case where the equipment subject to construction is present as the existing equipment and is also related to the newly established construction. CONSTITUTION:A work station 6 extracts one piece of data from constructed equipment drawing data 4b, successively collates them with equipment drawing data 4a and judges whether or not the equipment subject to construction is present as the existing equipment. When it is judged that the equipment subject to construction is present as the existing equipment and is related to the newly established construction, an identification code for identifying logical discrepancy is added to the data of the equipment related to the newly established construction so as to prevent confusion in the case of simultaneously screen-displaying the existing equipment and the equipment subject to construction. Thus even when construction data are transferred from a host computer 1 without any relation to the original flow of the construction, no logical discrepancy is caused.</p> |
